The problem isn't so much that the trace message were missing. I assumed that they only occurred when smtpd -d was used. As a result I didn't immediately update the smtpd_flags using rcctl. It is nice to know why the trace entries were no showing up.
But what bothered me was the thousands of lines in /var/log/messages saying sendsyslog: dropped 2 messages, error 55 when I first noticed I had forgot that I had modified smtd_flags and had no idea why my log files were filling up. I had no success trying to find what error 55 was. There was no hint as to what the source of the problem was. I did not know of any approach to find the cause, other than guessing that it was smtpd. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Todd C.

You'll need to edit /etc/syslog.conf and change: mail.info /var/log/maillog to: mail.debug /var/log/maillog Then you should see the trace information. - todd
